Fossilized Dinosaur Vomit

FortKnox writes: "Yeah, I didn't believe it either, but British scientists believe they have found fossilized vomit from a marine dinosaur. Its from a Jurassic period dinosaur. Apparently, fossilized vomit has been found before, but this is the oldest. So, next time you vomit, imagine who might find it in the far distant future...."

Humans are the only species disgusted by vomit...

Mainly because, as social animals, we developed the ability to regurgiate possibly bad or poisonous food on instinct, rather than wait for it to start harming us.

Most other animals have a much more egalitarian approach to vomit. Birds habitually regurgitate partially digested food to feed their chicks. Ever wonder why your dog wants to lick your face? In the wild, this behavior by puppies stimulates adult wolves to 'share' their kill with their young by vomiting back up.

In the article, it goes on about how many animals have a staple food that they simply cannot digest all of. In this case, the dino couldn't digest the shells it was eating the meat out of. Instead, it simply puked them back up rather than damage its intestine. The same thing happens today in whales, who spit the beaks of squid back out after it digests them.
